논문초록 When medical devices come into contact with blood, they undergo non-specific protein adhesion and denaturation, which can lead to thrombosis, inflammation, and device failure. We developed a biocompatible, superhydrophilic antifouling and antithrombotic gel-like coating to mitigate these issues. This coating is engineered through layer-by-layer assembly of poly-L-lysine, laponite (disc-shaped clay particles), and heparin, utilizing eletrostatic interactions. The inner layer forms a gel-like structure with laponite, maintaining superhydrophilicity to prevent protein and cell adhesion. Meanwhile, the outer heparin layer acts to prevent blood clot formation by inhibiting plasma protein adsorption and platelet activation. This coating retains its superhydrophilic properties and heparin stability after immersion in PBS for seven days, demonstrating its potential applicability across various implantable medical devices.
